A least squares regression line was calculated to relate the length (cm) of newborn boys to their weight in kg. The relationship between Length and Weight has an Rsquared of 58.6%. Write a sentence (in context) summarizing what the Upper R squared says about this regression.
Answer:
58.6% of the variation in length (in cm) of new born boys and their weight (in kg) is explained by the line of best fit.
Step-by-step explanation:
Given the following :
R² value = 58.6% comparing the length (cm) of new born boys to their weight (kg)
The R² value is called the Coefficient of determination. It is obtained by taking the square of the correlation Coefficient (R). The value gives the proportion of Variation between the independent and dependent variables which is explained by regression line. In the scenario above, the R² value means that 58.6% of the variation in length in centimeter of new born boys and their weight (in kg) is explained by the line of best fit. While (100% - 58.6% = 41.4%) is due to other factors.
Turn y=1/2x + 3/2 into standard form
=============================================
Work Shown:
y = (1/2)x + 3/2
2y = x + 3 .... multiply every term by the LCD 2
2y-x = 3 ... subtract x from both sides
-x+2y = 3
x-2y = -3 ... multiply both sides by -1
The last step is done so that the x coefficient is positive
The equation is in the form Ax+By = C with
A = 1B = -2C = -3You could have your answer as -x+2y = 3, since that is also in standard form. But many math textbooks make A > 0.
5% commission rate of 14.98 is what?
Answer:
$0.75
Step-by-step explanation:
To find the answer we simply multiply the amount of money earned by the percentage.
So the total amount of money = $14.98
And the percentage = 5%
But I order to calculate this we must first turn the percentage into a decimal. To do this we decide the number of the percentage by 100
In this case that is 5/100=0.05
We can now multiply this by the amount of money to get 0.05*14.98=0.749
We then round our answer to two decimal places (because money can not go past two) to get $0.75

Which type of demand has been created?
When the mortgage rates get high, the housing market will collapse, as fewer people will take loans for buying houses because of higher interest rates, and this will result in a demand.
Answer:
Scarce demand / inflation
The word "scarce" means low on supplies or anything else.
Inflation is the term used when a price increases in the market.
These two terms together would best describe the higher demand.
Hope this helps, have a great day! ♥

√6 + √5
please help me answere this qustion in STEP - BY - STEP solution
Answer:
√6 + √5= 4.69
Step-by-step explanation:
First, simplify the radicals-
in this situation, we have nothing to simplify.
√6 = aprx 2.45
√5 = aprx 2.23
√6 + √5= 4.685
= aprx 4.69
Does the relation in the table represent direct variation, inverse variation, or neither? If it is direct or inverse variation, write an equation to represent the relation. Explain your answer.
Answer:
Indirect variation
Step-by-step explanation:
If two variables change in inverse proportion, then it is called indirect variation.
xy = k where k is a constant.
5*2 = 10
10*1 =10
[tex]15*\dfrac{2}{3}=5*2=10\\\\\\20*\dfrac{1}{2}=10[/tex]
So, this is indirect variation.

Which expression is equivalent to |18|+ |-7|?
Answer:
18+7
Step-by-step explanation:
What is the value of s?
Answer:
s = 26°
Step-by-step explanation:
The total degrees of a triangle is 180°
1. Create the formula: [tex]180=50+2s+3s[/tex]
2. Solve for S
[tex]180=50+2s+3s\\180=50+5s \\ 180-50=5s \\ 130=5s\\\frac{130}{5} =s \\ 26=s[/tex]
3. Check by plugging in 26
[tex]180=50+2(26)+3(26)\\ 180=50+52+78\\ 180=180[/tex]
Jeff earns money mowing lawns. His earnings and hours worked represent a direct variation. He worked for 5 hours and earned $37.50. Determine the constant of proportionality for dollars earned per hours worked and for hours worked per dollars earned.
Answer:
$7.50 are earned per hour
Step-by-step explanation:
5x = 37.50
divide both sides by 5
x = 7.50

Ben is traveling to Santa Cruz and needs a full tank of gas. A full tank of gas gives him a total of 260 miles until empty. So Ben goes to the gas station to fill up his tank but he only has $11.86. If $11.86 only gives Ben a total of 60 miles until empty, how much money does he need in all, to get a full tank of gas to drive to Santa Cruz? Round your answer to the nearest dollar. ?
260 miles / 60 miles = 4 1/3
He would need 4 1/3 more gas:
11.86 x 4 1/3 = 51.39
he would need $51.39
Please help if you can.
What is the quotient. Of 25)9250
Answer:
370
Step-by-step explanation:
Isolate the numbers so that you are only dividing sections at a time.
So 25 goes in to 92 three times. so we multiply 25 by three and subtract that from 92. Put the three at the top and repeat throughout.
92-75=17
Bring the next number down and repeat.
Answer: 370 Remainder 0

HELP PLS find measure of w in this trapezoid
Answer:
m<w= 36°
Step-by-step explanation:
Step 1) Applying geometric and algebraic knowledge, the two angles to the left are both 90, and equal to 180. If you add those two angles and the 146°, you will be given 326 in total.
90+90= 180 +146 = 326
Step 2) With knowledge that the sum of all interior angles inside of a quadrilateral add up to 360, subtract 326 from this.
360-326=36
Final product: m<w=36°

SV is a midsegment of △RTU.
If TU=y+38 and SV=y–9, what is the value of y?
Answer:
y = 56
Step-by-step explanation:
the midsegment SV is half the length of the side TU , that is
y - 9 = [tex]\frac{1}{2}[/tex] (y + 38) ← multiply both sides by 2 to clear the fraction
2y - 18 = y + 38 ( subtract y from both sides )
y - 18 = 38 ( add 18 to both sides )
y = 56
